A communication system includes an earth station configured to receive a downlink transmission from a satellite and transmit an uplink transmission to the satellite. The communication system further includes a server in operable communication with the earth station, a beacon detector in operable communication with the server, an access point configured to operate within a proximity of the earth station, and a beacon transmitter disposed within close proximity to the access point. The beacon transmitter is configured to transmit a beacon signal to one or more of the server and the beacon detector. The beacon signal uniquely identifies the access point. The server is configured to implement a measurement-based protection scheme with respect to at least one of the downlink transmission and the uplink transmission.

1. A communication system, comprising: an earth station configured to receive a downlink transmission from a satellite and transmit an uplink transmission to the satellite; a server in operable communication with the earth station, and configured to implement a measurement-based protection scheme with respect to at least one of the downlink transmission and the uplink transmission; a beacon detector in operable communication with the server; a first access point and a second access point configured to operate within a proximity of the earth station; and a first beacon transmitter disposed within close proximity to the first access point, and a second beacon transmitter disposed within close proximity to the second access point, each of the first and second beacon transmitters configured to respectively transmit, to one or more of the server and the beacon detector, a beacon signal uniquely identifying the respective access point.
2. The communication system of claim 1 , wherein the first access point comprises a first antenna subsystem and the second access point comprises a second antenna subsystem.
3. The communication system of claim 2 , wherein the first antenna subsystem comprises a multi-antenna wireless transceiver.
4. The communication system of claim 3 , wherein the second antenna subsystem comprises a directional antenna.
5. The communication system of claim 3 , wherein the multi-antenna wireless transceiver includes a multiple input multiple output (MIMO) antenna.
6. The communication system of claim 3 , wherein the multi-antenna wireless transceiver is configured to implement at least one of beamforming and null forming.
7. The communication system of claim 6 , wherein the multi-antenna wireless transceiver is further configured to implement the beamforming and the null forming with respect to one or more mobile user equipment devices.
8. The communication system of claim 6 , wherein the multi-antenna wireless transceiver comprises a multi-antenna transceiver array.
9. The communication system of claim 8 , wherein the multi-antenna transceiver array is configured to implement the beamforming and the null forming with respect to a fixed wireless access subsystem.
10. The communication system of claim 8 , wherein the multi-antenna wireless transceiver is further configured to implement both beamforming and null forming simultaneously for transmission of a mobile downlink of a first cell covered by the multi-antenna wireless transceiver.
11. The communication system of claim 10 , wherein beams of the beamforming and nulls of the null forming are generated from a central processor configured to cooperate with the multi-antenna transceiver array.
12. The communication system of claim 11 , wherein the central processor is further configured to generated the beams and nulls based on at least one of channel status and system information.
13. The communication system of claim 11 , wherein the generated beams comprise a plurality of beams directed toward a plurality of respective mobile subsystems, and wherein the generated nulls comprise a plurality of nulls directed toward a plurality of respective satellite subsystems.
14. The communication system of claim 13 , wherein the central processor is further configured to generate a first null for a first satellite subsystem and a second null for a second satellite subsystem, wherein the first satellite subsystem is located farther from the earth station than the second satellite subsystem, and wherein an attenuation of the first null is greater than an attenuation of the second null.
15. The communication system of claim 10 , wherein the central processor is further configured to transmit the generated beams and nulls forming at a different frequency from a frequency of operation of the earth station.
16. The communication system of claim 10 , wherein the central processor is further configured to maximize a downlink signal to noise ration from the multi-antenna transceiver array at respective user equipment devices of a mobile subsystem.
17. The communication system of claim 8 , wherein the multi-antenna wireless transceiver is further configured to implement beamforming for transmission of an uplink of a second cell covered by a beam pattern of the multi-antenna transceiver array.
18. The communication system of claim 16 , wherein the multi-antenna wireless transceiver comprises a receiver portion configured to adjust the uplink from a fixed or mobile subsystem.
19. The communication system of claim 10 , wherein the central processor is further configured to generate at least one beam within at least one null.
20. The communication system of claim 10 , wherein the central processor is further configured to generate a first null within a second null.
